may be welded at this point, as by electric spot Welding, to effect the union spoken of. The dependingportion 6 of the reinforcing flange a, not only serves to stiffen the flange, at the rear against deflection or (hSt-OIUOII in handling and under strains but also provldes a convenient flat attaching flange for reinforcing or tieing straps 7 which extend;

transversely across the sheet and serve to stiffen the section; said strap being attached to the flanges 6 in any desirable manner, such as by rivets or like fastening means or by welding, if desired. It will also be noted that the depending portions 6 form a wide, flat bearing face for the studs or joists 8, obviating a liability of injurious kinking or deflection of the reinforcing flanges of the sheet, in application of the studs and in the exertion of pressure there against due by introduction of the concrete or plastic material within the form. However, the

flanges 6 also perform another function in that they may act as guides or stops forv In setting up the mold sections, any suitable backing or main reinforclng posts, bars or beams may be employed, as is usual in the erection of molding formations of this However, as shown in Figs. backing or reinforcing member 8, comprls- 'mg suitable conventional sections 9, which may be formed in short lengths to facilitate assembling and ready resetting of the mold;

sections. For instance, as shown in Figs. 10 and 11, the members 9 may overlap and be united by suitable fastening means 10 comprising studs carried by one member and adapted to be tied to the web of the other member, as by tapered wedge keys 11 pass- "ing therethrough. By employing wedge keys, the sections may be readlly disconnected when it is desired to remove or otherwise shift or adjust said sections. At the point where one section 9 joins the other, the mem-- bers are preferably so spaced as to provide an intermediate opening or pocket 12,. through which a tie rod 13 may be passed,

such tie rods being usually employed to lock opposing sections of a mold 1n proper position agamst displacement or distortion in applications or setting of the plastic material. The tie rods may also carry a suitable;

reinforcing brace of commercial sections 14,

such as channels placed back to back running transversely and back of the reinforced sections 8, said tie rod being provided with the usual clamping nut 15. The reinforcing members 8 may be of any suitable shape such as the channels shown or an angle section Z bar, or similar structure. Such structures are usually'employed not only because of the great stiffness afforded with the minimum of metal but also because of the provision of thin web or flange portions to which auxiliary pieces, such as the sections 16, may

be attached where the requirements or eXigencies of the case demand it.

Any suitable means may be employed for tying the mold section to the reinforcing posts or members 8.

openings or eyes 17, through which a flexible tie member such as wire, may be passed, and by which the section' may be securely anchored to said studs or joist or section 8.

The contiguous sectionsv may be united to one another in different ways. For instance, as illustrated in Fig. 2, the end or edge reinforcing flange 4 is shown as having the continuation 18, which may be spread from the For instance the L-. shaped flangesa may have suitable 'lIOlGf wall 19 sufliciently to permit of the inter-r1 positioning or interlocking of the large angular flange 20 of the adjoining section; the member 18 having an angular flange 21 which serves to readily guide the flange 20 upon insertion thereof between the portions 18 and 19.

As illustratedin Fig. 3, the mold section 3 is shown as being formed of a plurality of separate sections 3, which may be united by suitable fastening means 5' and, tied to the strip 7, as in the case of sections as shown in Fig. 1;

In Figs. 4 and 5,1 show modified means for providing a light reinforcing member 4:

corresponding in function to the member i described in connection with Fig. 1. As shown in Fig. 4:, the sheet 2 has a comparatively short fold 1, which not only serves-to reinforce the sheet but also provides fastenin g means in application of the angle mem-' ber 49 thereto. 'In Fig. 5, I illustrated the section 4 as having secured thereto the two separate sections 2*, instead of providing the continuous fold as shown in Fig. 4. In referring to both of these views, it will be understood that the fastenings '5 are preferably so positioned near the body of the. sheet as to prevent opening of the sheet at the molding face thereof.

r I By referring to Fig. 6, it will be seen that by my improved mold, sections may be readily looked as to enable convenient and ready longitudinal adjusting of the sections in the building 'up of the mold or disassembling thereof. And as brought out in Figs. 1 and 12 the ends of the. sheets may have the extensions 22 or lap'formed in theintegral with the sheet. or comprising a separate piece 24 connected tothe body of the sheet, as shown in Fig. 12; the purpose of said ex Etensions being to afford a lapfor end interlocking of the sheets as they are assembled.

In Fig. 7, Iindicate a modified manner of reinforcing themolding sheet 2. It consistsj in providing an irregular backing sheet or a above described; In this case, the member strip 23 in lieu of the flanged members 4 23 is shown as being substantially a corrugated sheet to which. may be applied the stiffening strips 7, above described. I In Fig. 8, another form of reinforcement is shown. It comprises the Z-bar 24:, to

which may be riveted or otherwise applied .the sheet 2. This Z-bar construction has the a j i advantages of the L-reinforcement shown in Fig. 1, in so far as concerns its reinforc ing quality and convenience of attachment;

to the auxiliary reinforcing means or brace. Iing posts or bars. Instead of employing a g 3 Z-bar, a channel shape 24" may be used 25 lieu thereof, as shown in this View.

It will be apparent from the foregoing description that in building up themold, said mold may take different shapes in accordance withthe requirements of the par= ticular structure contemplated. By reason of the simplicity of construction, lightness of weight and the facility of adjustment, there is practically no limit in the formation ofdesired molding shapes. For instance, as

shown in F ig. 9, a plurality of mold sections 25, constructed in accordance with my invention maybe employed in conjunction l with suitable angle corner pieces 26,

forming beams, columns, etc.; the corner sec tion 26 permittingof relative adjustment of the main mold sections 25. The advantages of my invention will bel :appreciated by those skilled in the art. I

ynOt only provide a mold in which simplicity of construction and minimum amount of metal obtain, but also a mold whichmay be easily set up. and taken down.

Instead of the conventional rolled shapes;

shown, such sections may be rolled or pressed up out of sheet metal.

Having thus described my invention, what. I claim and desire to secure by Letters Patent is:

f 1. .In a mold of the character described, a wall composed of afl plurality of sections, each section consisting of. a wall portion. formed of sheet metal and a plurality of an- 1 gularly projecting reinforcing integral :flanges, having end folds extending at an 2.

wall composed of similar sections, each sec- ;tion consisting of a wall portion formed of sheet metal and a plurality of flanges angularly disposed along the section and each comprising an intermediate flange and a lon gltudinal edge flange on sa1d lntermed ate flange at an angle theretoformed by folding the body of the sheetmetal.

. 3. In a mold ofthe character described, a

i wall composed of similar abutting sections, g each section consisting of a. wall portion formed of sheet metal and having a plural ity of integral flanges along its length and angular-1y disposed with regard to the body of the sheet, said plurality including end flanges interlockingjivvith end flanges ofan adjacent section and also including flanges formed by a fold ofmetal of the sheet and intermediate said end flanges, and separate means for reinforcing the sections. a

.4. In a concrete form section, a mold wall section of thin sheetmetal carrying a plurality of reinforcing flanges at its back, each,

.such flange being formed by an L-shaped double fold of the sheet metal, and a plurality of tie strips secured to the ends. of the flanges.

5. In a Wall mold for concrete, a mold face comprising a plurality of abutting sections of sheet metal, each sheet of metal being a .folded to produce an L-shaped bracing flange having a part in a plane parallel to said sheet and vertical connecting means for saidparts. 6. Ina mold, a mold wall formed of a plurality of sheet metal sections in abutting 1 engagement, each such sectlon having lateral L-shaped integral flanges at each end adapted to engage the corresponding flange of an adjacent sheet and also adapted to enstantially right angles to such section and formed by a fold of the metal intermediate its ends.
